Bryan Litz and The Science of Accuracy Academy has done a Podcast with vital information for all handloaders. This Podcast examines the effects of humidity variances on powder. Bryan notes: “If you want to know how much this can matter, we’re talking up to 200 fps difference for the same load of H4350 in 6.5 Creedmoor” at opposite extremes of humidity.
Bryan adds that “Most shooters don’t realize what a big deal this can be — it overshadows many of our efforts to make consistent velocity and hit targets. This can happen in loaded rounds not just for hand loading where you expose powder to ambient humidity. This is especially important for hunters considering the range of environments hunting ammo goes through.”

Sierra BulletsBallistic Technician Gary Prisendorf has written a nice essay about how reloading can become a life-time hobby, a rewarding pastime that can bring together a father and son…
Memories of My Father — Reloading As a Life-Time Hobby
by Gary Prisendorf
For as long as I can remember I have been around reloading. I have tons of childhood memories of my father reloading and shooting. I remember how he would let me help him load his ammunition, by letting me clean primer pockets or wipe the sizing lube off of his cases. I really thought I was doing something. Well, I guess I was, I was spending quality time with my father doing something that would become a great hobby and eventually land me a great job working for Sierra Bullets.
If you are a reloader, teach someone. You may just give them a hobby for the rest of their life and who knows, you could help them find an enjoyable career, doing something that they love.
— Gary Prisendorf
I remember watching my father sizing cases on his Herters press, dropping his powder charges with a Belding & Mull powder measure and weighing powder charges with his Texan scales. Heck, I can even remember when he would buy powder at a local pawn shop, and they would weigh it out and put it in a paper sack. He would save his empty powder cans, wrap them with masking tape and write what the powder was on them with a black magic marker.
When I was in Junior High, I got my first shotgun, a 20 gauge Mossberg 500 and within a couple of weeks my father came home with a 20 gauge Lee Load-All and a pound of Blue Dot. He gave me a crash course on how to use it, and got me up and running with a couple of safe loads. I put a lot of shells through that old 20 gauge.
From that day forward I was hooked. If I got a new gun, I was loading ammunition for it. I don’t buy factory ammunition unless I just want to shoot it up so I can get some once fired brass. I reload everything that I shoot, except for rimfire stuff, and if I could figure out how to do that safely, I would probably load that too.
Through the years I have learned to appreciate things — such as once-fired military .30-06 cases that can be converted to obscure cartridge types. And I know the value of a five-gallon bucket of lead wheel weights that will be melted down and cast into bullets.
I remember finding 19 once-fired Norma 7.7×58 Arisaka cases laying on the ground at a public shooting range, and it was like Christmas came early. I must have looked for that 20th case for about thirty minutes, but I never did find it.
I can’t thank my father enough for getting me started in reloading, he gave me a great hobby, many wonderful memories and taught me the skills that gave me a career doing something that I love.
The U.S. Army Marksmanship Unit regularly publishes reloading “how-to” articles on the USAMU Facebook page. One very good article, part 5 of a 6-part series, focused on Progressive Presses. This article explains proper procedures for Auto-Indexing Progressives, which advance the shell-plate with every pull of the handle. Auto Progressives are very efficient, but they also require special attention and focus, because so many things are happening at once. You need to train yourself to watch every station. If you run a progressive press now, or are considering getting a progressive, we recommend you read this article. Visit the USAMU Facebook page for other helpful handloading guidance.
Progressive Loading Presses — Self-Advancing Shellplate Type
Recently, we addressed manually-operated progressive presses for the beginning handloader. This type press requires one to manually advance the shellplate after each handle stroke. An advantage for beginners is that nothing happens at any station until the loader wants it to. This helps users avoid problems from clearing malfunctions without noticing that the shellplate has advanced itself. (Read Previous USAMU Article on Manual Progressives.)
The next, more luxurious type progressive press advances the shellplate automatically whenever the handle is cycled. [Editor: This is also called an “Auto-Indexing” Progressive Press.] Typically, each stroke automatically sizes and primes a case, operates the powder measure (if used) and seats a bullet. Some also have case feeders that automatically put a new case in the shellplate with every cycle. Others require the loader to insert a case each cycle. With both types, the loader usually puts a bullet on each sized/primed/charged case.
[CAVEAT: While our Handloading Shop has several progressive presses, ALL of our powder charges are thrown/weighed by hand. We do not use powder measures on our presses. Our progressives are used for brass preparation, priming, seating, etc., but not for fully-progressive loading.]
The manually-advanced press can be a boon to beginners, but as one gains experience it can be a mixed blessing, depending on one’s style. If one pays close attention to every operation and loads without distractions, the manual press is very reliable and allows full scrutiny of each round as it is loaded. However, if one easily drifts into day-dreaming, or isn’t focused on paying careful attention at all times, the manual progressive can be a bit of a liability. The opportunity for forgetting a powder charge, leading to a squib load, is ever-present. [Editor: A lock-out die can help reduce the risk of a squib load, or a double-charge. See below.]
The automatically-advancing progressives help prevent this by ensuring a powder charge will be dropped each time the handle is operated. Experienced handloaders often appreciate this feature due to the savings of time and effort. Individual preferences between the two press styles are influenced by several factors. These include one’s comfort with more- vs. less-complicated mechanisms, how often one changes calibers (case feeders often must be converted, in addition to dies and shellplates), how many rounds one loads annually, relative ease of changing primer mechanisms from small to large, etc. Automatic progressives and their caliber conversion kits tend to be significantly more expensive than manual progressives and caliber conversions from the same maker.
One USAMU handloader, who likes simple, bullet-proof machines and maximum efficiency when converting presses, owns two manually-advanced progressives. One is set up for large primers, and the other for small primers. He can change calibers in the twinkling of an eye. As he loads for many different calibers, this fits his style. Another handloader here is just the opposite. He loads for a few calibers, but in larger quantities. He much prefers his self-advancing press with case-feeder for its speed. He makes large lots of ammo in a given caliber before switching, to improve overall efficiency. His caliber conversion kits are more expensive than those for the manually-advanced progressive, but he uses fewer of them.
Whichever type one chooses, it is VERY important to buy quality gear from a manufacturer with a long, well-established track record for quality, durability and good customer support. Avoid jumping on the “latest, greatest” model until it has a proven track record. For example, this writer knows a loader who got a brand-new, expensive, self-advancing model press some years back, shortly after its introduction. As is too often the case these days, the manufacturer released it before all the “bugs” were worked out.
Better Safe Than Sorry — the RCBS Lock-Out Die
RCBS Makes a “Lock-Out Die” that senses the powder charge. This will halt the Progressive press if you have a double charge, or an undercharge. Your Editor has the Lock-Out Die on his RCBS Pro 2000. It has “saved his bacon” a half-dozen times over the years. It can be used on Dillon and Hornady progressives as well as RCBS machines.
It would not fully seat primers to the correct depth. No amount of adjustment, extra force, or fiddling would do better than to seat primers barely flush with the case head. Any inattention could result in a slightly “high” primer, protruding above the case head. It created a risk for slam-fires, particularly in semi-autos without spring-retracted firing pins, such as the M1 or M1A. In desperation, he had a machinist buddy study the problem and machine a new part to correct it. No dice. Its engineering didn’t permit full primer seating, even with extended parts. He now wishes he’d heeded his shooting buddies’ advice to stick with the “tried and true,” reliable performer they all used.
Whichever press one selects, see if the maker has a kit or list of commonly-replaced parts. Having needed springs, pins, etc. on hand in the rare event that one breaks or “goes missing” can save the day when one is busy loading for a match! Another tip for improving one’s overall loading efficiency (rounds loaded with minimal set-up/tear-down time) is to plan one’s handloading by primer size. For example, if your machine is set to use small primers, load all the calibers that you intend to that take small primers, before converting the press to load large-primer calibers.
In our next chapter, we’ll discuss peculiarities of progressive loading for rifle cartridges, with remedies for problems such as excessive cartridge-case headspace variation when sizing, tips for ensuring best powder charge consistency, and so on. Until then, be safe, and good shooting!
Figure 1. When the bullet is seated farther out of the case, there is more volume available for powder. This enables the cartridge to generate higher muzzle velocity with the same pressure.
Effects Of Cartridge Over All Length (COAL) And Cartridge Base To Ogive (CBTO) – Part 1 by Bryan Litz forBerger Bullets.
Many shooters are not aware of the dramatic effects that bullet seating depth can have on the pressure and velocity generated by a rifle cartridge. Cartridge Overall Length (COAL) is also a variable that can be used to fine-tune accuracy. It’s also an important consideration for rifles that need to feed rounds through a magazine. In this article, we’ll explore the various effects of COAL, and what choices a shooter can make to maximize the effectiveness of their hand loads.
Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI)
Most loading manuals (including the Berger Manual), present loading data according to SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute) standards. SAAMI provides max pressure, COAL and many other specifications for commercial cartridges so that rifle makers, ammo makers, and hand loaders can standardize their products so they all work together. As we’ll see later in this article, these SAAMI standards are in many cases outdated and can dramatically restrict the performance potential of a cartridge.
Bullet seating depth is an important variable in the accuracy equation. In many cases, the SAAMI-specified COAL is shorter than what a hand loader wants to load their rounds to for accuracy purposes. In the case where a hand loader seats the bullets longer than SAAMI specified COAL, there are some internal ballistic effects that take place which are important to understand.
Effects of Seating Depth / COAL on Pressure and Velocity
The primary effect of loading a cartridge long is that it leaves more internal volume inside the cartridge. This extra internal volume has a well known effect; for a given powder charge, there will be less pressure and less velocity produced because of the extra empty space. Another way to look at this is you have to use more powder to achieve the same pressure and velocity when the bullet is seated out long. In fact, the extra powder you can add to a cartridge with the bullet seated long will allow you to achieve greater velocity at the same pressure than a cartridge with a bullet seated short.
When you think about it, it makes good sense. After all, when you seat the bullet out longer and leave more internal case volume for powder, you’re effectively making the cartridge into a bigger cartridge by increasing the size of the combustion chamber. Figure 1 illustrates the extra volume that’s available for powder when the bullet is seated out long.
Before concluding that it’s a good idea to start seating your bullets longer than SAAMI spec length, there are a few things to consider.
Geometry of a Chamber Throat
The chamber in a rifle will have a certain throat length which will dictate how long a bullet can be loaded. The throat is the forward portion of the chamber that has no rifling. The portion of the bullet’s bearing surface that projects out of the case occupies the throat (see Figure 2).
The length of the throat determines how much of the bullet can stick out of the case. When a cartridge is chambered and the bullet encounters the beginning of the rifling, known as the lands, it’s met with hard resistance. This COAL marks the maximum length that a bullet can be seated. When a bullet is seated out to contact the lands, its initial forward motion during ignition is immediately resisted by an engraving force.
Seating a bullet against the lands causes pressures to be elevated noticeably higher than if the bullet were seated just a few thousandths of an inch off the lands.
A very common practice in precision reloading is to establish the COAL for a bullet that’s seated to touch the lands. This is a reference length that the hand loader works from when searching for the optimal seating depth for precision. Many times, the best seating depth is with the bullet touching or very near the lands. However, in some rifles, the best seating depth might be 0.100″ or more off the lands. This is simply a variable the hand loader uses to tune the precision of a rifle.
Creedmoor Sports has released a series of helpful “how-to” videos in its new InfoZone web page. In the latest InfoZone video Bill Gravatt shows how to seat bullets using L.E. Wilson Hand Dies and an Arbor Press. The basic process is simple, particularly with a micrometer-top seating die. That makes it easy to adjust and set seating depth. Before you start seating bullets, you want to adjust the height of the arbor so the stroke is appropriate to the height of your die.
Bill Gravatt Shows How to Use Hand Seating Dies — Creedmoor INFOZONE
ARBOR PRESS TECHNIQUE: When using an arbor press, smooth is good. You don’t want to slam the handle down quickly. Try to repeat the same motion each time. You can also experiment by seating the bullet part way, then rotate the cartridge (in the die) and do the final seating with a second stroke. If your arbor press has a force gauge, note both the max value of the gauge needle and how it moves as you seat the bullet. If the needle spikes too rapidly, or bounces back and forth irregularly, set that cartridge aside and/or mark it. You could have neck tension issue with that case or some other fault. You might even have a bad bullet. That’s rare, but can happen. The key to success is moving the press arm in a smooth motion every time, maintaining the same down-pressure with each cartridge.
Here Bill Gravatt Offers a Simple Tip for Adjusting Wilson Seating Dies
One of our Forum readers asked “How can I get a custom in-line seater for my new rifle?”. First, we would say that, if you are not shooting an unusual Wildcat, check first to see if L.E. Wilson makes a stainless Micrometer Seater Die for your rifle. These dies are a joy to use, and we’ve found the fit to be exceptionally good with many calibers. Typically priced from $95-$115, Wilson stainless micrometer-top seaters are available for dozens of cartridge types: .204 Ruger, 20 BR, .222 Rem, .223 Rem, 22 PPC, 22 BR, .22-250, .223 WSSM, 6 PPC, 6mmBR, 6XC, 243 Win, .243 WSSM, 25 WSSM, 6.5×47 Lapua, 6.5 Creedmoor, 6.5-284, 26 Nosler, .270 WSM, 7mm-08, .284 Win, 28 Nosler, 7mm RUM, 30 BR, 30 IHMSA, .308 Win, .300 WinMag, .338 Edge (and MORE).
If you do want a custom seater die, the process is relatively simple. Purchase a die blank from Wilson and have your gunsmith run the chambering reamer in. Forum member Gunamonth explains: “I start with a Wilson seating die blank. They’re available from Sinclair and other vendors. Just run the reamer in. For some of my rifles, where I wanted the stainless die with the micrometer adjustment, I bought a smaller die and had the smith ream it with the chamber reamer. That’s how I had my 6 Dasher and 6mm AI seaters made. With the Dasher I stared with a 6mmBR Micrometer die.”
SEATER STEM TIP: If, on your seated bullets, you are seeing a sharp line around the jacket near the ogive, you may want to smooth out the leading edge of the Wilson seater stem (see above left). Do this by putting a little lapping compound on one bullet and manually spin this around in the stem. Without much effort you’ll have a smooth bullet/stem interface.
Micrometer Top Add-on
We really like micrometer tops on a seating die. But what if Wilson doesn’t make a micrometer top seater for your chambering? Don’t despair, Brownells sells a $39.99 Sinclair Micrometer Top that can be added to Wilson standard seaters or to a custom seater die made from a Wilson die blank.

Fire-Form with Foulers
Here’s a tip for guys who shoot the 6 PPC, 6 Dasher, 6 BRA, .284 Shehane, or other wildcat cartridges that require fire-forming. Use your fouler shots to fire-form new cases. That way your fouler shots do “double-duty” and you get your brass fire-formed without putting extra rounds through your expensive barrel.
This procedure is recommended by Joel Kendrick, the 2004 IBS 600-yard Shooter of the Year. After he cleans his barrel, Joel knows it takes two or three shots to foul in the bore before accuracy returns. (YMMV — some barrels may need five or six foulers.) When shooting his PPC, Joel uses those fouler shots to fire-form his new brass. Joel explains: “I like to have relatively new brass always ready. By fire-forming a couple cases after each barrel-cleaning during a match, by the end of the weekend I’ve got a dozen or more freshly fire-formed cases to put into the rotation. If you do this with your fouler shots you get your fire-forming accomplished without using up any extra barrel life.”
This not only saves barrel wear, but it saves you trips to the range for the purpose of fire-forming. We thank Joel for this smart suggestion. For those who do not have a dedicated barrel for fire-forming, this should help keep your round-count down. Note: With this fouler fire-forming routine, you should ALWAYS do the fire-forming with the SAME POWDER you load for your match ammo. Joel currently works as the Supplier Quality Process Engineer for MMI-TruTec, a company that offers barrel surface coatings that can further extend your barrel life.
Vista Outdoor has announced that it will be raising prices on ammunition, primers, and powder starting January 1, 2024. Last week, the Minnesota-based company sent a letter to commercial customers revealing across-the-board cost increases for ammunition, primers, and powder starting the first of the year. The price increases will range from one percent to ten percent, with projected 5% price hikes for primers. CCI/Federal/Remington .22 LR rimfire ammo will rise 1-5% while rifle ammo goes up 1-7%.
“Due to world events our suppliers have notified us of unprecedented demand for and an anticipated global shortage of gunpowder, and thus has increased our prices substantially,” Vice President of Sales, Sporting Products Brett Nelson said in the letter. “We must therefore raise our pricing to help offset those increases.”
Vista Outdoor Sporting Group entities that will increase prices include Alliant Powder, CCI, Federal, Remington, Speer, and HEVI-Shot. The projected increases are shown at right.
What’s the next best thing to a stockpile of gleaming, freshly-loaded ammo? How about a movie showing gleaming, freshly-loaded ammo being made — from start to finish? The five-minute video below shows the ammunition production process at the Lake City Army Ammunition Plant in Independence, Missouri. Lake City is the largest producer of small arms ammunition for the U.S. military, producing roughly four MILLION small-caliber rounds every day.
This promotional video does go overboard at times (too many smiling employees gushing about quality control). Still, it is fascinating to watch the process of creating cartridges — from the drawing (or extrusion) of raw brass into casings to the placement of projectiles and primers.
Quick History of Lake City Ammunition Plant Lake City Army Ammunition Plant (LCAAP) is a 3,935-acre government-owned, contractor-operated facility in Independence, Missouri that was established by Remington Arms in 1941 to manufacture and test small caliber ammunition for the U.S. Army. The facility has remained in continuous operation except for one 5-year period following World War II. Remington Arms operated the plant from its inception until 1985. Then Winchester took over the facility from 1985-2000.
Prior to its acquisition by Northrup Grumman in 2018, Orbital-ATK ran the plant since late 2000, initially as Alliant Techsystems (ATK). Recently Olin Corporation announced that its ammunition division, Olin Winchester, LLC, has been selected by the U.S. Army to operate and manage the Lake City Army Ammunition Plant for the next seven years — Winchester will assume full operational control of the Lake City plant on October 1, 2020.
Powder Valley has added Norma products to its extensive inventory of ammunition, reloading components, tools, and shooting accessories. Powder Valley is now carrying Norma products for shooters and handloaders.

About Norma Precision AB
Dedicated to outfitting shooting enthusiasts with quality products since 1902, Norma started out in a small Swedish town and is now a top global brand boasting more than 350 employees, most of whom are hunters, shooters, and reloaders themselves. For hunting and target shooting applications Norma manufactures many millions of rounds annually for 100+ different cartridge types.
VERY Informative Video Show Cartridge Brass and Ammunition Production:
Here’s a cool video showing how bullet, brass, and ammunition are produced at the Norma Precision AB factory. You can see how cartridges are made starting with brass disks, then formed into shape through a series of processes, including “hitting [the cup] with a 30-ton hammer”. After annealing (shown at 0:08″), samples from every batch of brass are analyzed (at multiple points along the case length) to check metal grain structure and hardness. Before packing, each case is visually inspected by a human being (3:27″ time-mark). The video also shows how bullets are made from jackets and lead cores. Finally, you can watch the loading machines that fill cases with powder, seat the bullets, and then transport the loaded rounds to the packing system.
